Table 2-4 Abnormal GPS Conditions Annunciated on HSI
Figure 2-42 Example of HSI Annunciations
DR Mode causes the following items on the PFD to be shown in yellow:
• CDI, when GPS is the selected navigation source. (Yellow CDI is removed after 20 minutes.)
• Current Track Bug
• Wind Data
• Distances in the Bearing Information windows
• GPS bearing pointers
It is important to note that estimated navigation data supplied by the G1000 in DR Mode may become
increasingly unreliable and must not be used as a sole means of navigation. See the Flight Management section
for more information about DR Mode
